CARVALHEIRA, Gianna Maria Griz et al. Cytogenetics of angiosperms collected in the State of Pernambuco: IV. Acta Bot. Bras. [online]. 1991, vol.5, n.2, pp.37-51. ISSN 0102-3306.

Chromosome numbers are reported for 22 species belonging to 19 genera of angiosperms collected in the State of Pernambuco. A table with the herbarium voucher, collecting sites, diploid numbers and previous chromosomes counts for all the species is presented. Eight of the species have no previous counts. For some species, two or more different chromosome numbers have been presented in the literature. Our data suggest that most of such disagreements might be due to the presence of satellited chromosomes with elastic secondary constriction. Furthermore, special cytogenetics features of every species are hereby presented and discussed.

Keywords : Chromosome number; Angiospermae.
